Partial quenching of fluorescence of MPS-PPM (10−5 M in “repeat units”) by B-MV (Upper) and MV+ (Lower) (quencher concentration 3.2 × 10−7 M in each case). In the upper plot, the fluorescence quenching is reversed by addition of 1.2 × 10−8 M and 3 × 10−8 M avidin whereas addition of similar amounts to the MV+-quenched sample (Lower) shows no increase.
